As long as we're discussing correct terminology, that "huge ring" is usually called an inertia ring. It's usually neutral balanced and any external balance weight is most often found cast into the hub.

A harmonic balancer is not to balance the reciprocating loads or centrifugal loads (unless its for external balanced engine) that nice big weight ("inertia ring") is to BALANCE the torsional vibrations.

And remember this.
I found this definition for Balance.
a condition in which different elements are equal or in the correct proportions.

And is what dampening is. To counter act or damp or absorb.
People seem to get too hung up on centrifugal balancing forces, that is NOT what a harmonic balancer is for, except in the condition stated above.
Old timer engineers in the mid 50's termed them as harmonic balancers, the term fits. Its just like the fanaticism between "foot pounds of torque" and "pounds feet of torque" both terms mean the exact same thing. Damper - Balancer.

I get a kick out of that one too. The commutative property of multiplication means either way is totally right, but for whatever reason "pound feet" sounds weird to me. I always heard "oil galley" too, until I started branching out and researching from other places, and started seeing "gallery". The rationale behind "gallery" definitely makes it seem like the more appropriate term.

Also, if you want to see a fun trick, hook me up to blood pressure cuff and say the abomination "irregardless" around me and watch the magic as it shoots through the roof! That butchery of a word makes me physically angry.

Oh, and also shock absorbers. Can't forget that one. They are dampeners.

"irregardless" is in all the new dictionaries. If an incorrect word gets used enough ... it becomes an actual word.

Not until they are loaded and then since its a spring causing the load its called? But then a metallurgist may argue the point that yes the material is loaded, that is what makes metal what it is, the internal or molecular stresses.

Force and Pressure are completely different but, get used incorrectly for the same meaning all the time

But a spring will exert a pressure on the washer under it, and on the cylinder head.The retainer and keepers too.
If you wanted to know the "real" spring pressure, you'd measure the load at whatever height(spring tester), measure the area where the spring contacts the washer(or retainer, or keepers), then divide.

But you wouldn't get what you might think you get.
That might make a good topic?
